ASCO JB68A215C Pressure Switch

ASCO JB68A215C is a miniature J-Series pressure switch that provides a fixed 6.5–8.5 PSIG setpoint with SPDT (Form C) contacts. It features a 1/8" NPT pressure port for direct connection to pneumatic lines, a brass body with Buna-N diaphragm, and electrical ratings of 125/250 VAC (with a 28 VDC rating for DC control circuits). The device is non-adjustable with a fixed deadband, ensuring repeatable switching within the specified pressure window. This compact switch is designed for tight spaces in equipment such as small compressors, HVAC controls, and other pneumatic systems where reliable pressure sensing is required. Its combination of precise setpoint range, durable materials, and standard NPT port size makes it a practical choice for integration into control circuits that require a robust, relay-friendly pressure-sensing component.
